Objectives: After studying the article, you should be able to:

• Discuss the occurrence rate of proximal focal femoral deficiencies.

• Explain the types of proximal focal femoral deficiencies.

• Recognize concerning sonographic findings for proximal focal femoral deficiencies.

1. Proximal focal femoral deficiency is unilateral in what percentage of cases?

2. Which of the following proximal focal femoral deficiency types would best apply to the Aitken classification, which states that the femoral head is attached to the shaft by the femoral neck with mild shortening of the femur?

3. At birth, the baby from the Case Study section in this article had a lower limb-length discrepancy of ____, with the deficit on the left femur.

4. With sonography, a femoral diaphyseal length that is less than the ___ percentile for gestational age should raise suspicion for proximal focal femoral deficiency.
